heat/air
 

Winter is approaching and I am still without heat in my 1984 300DT. I made it through the summer without air, but another winter without heat I can't bear. It seems as though I have warm air coming out the vents and last year the fan would kick on at will for a few seconds and then quit. I replaced the switch and the monovalve but neither helped. The car seems to have many electrical quirks, I don't know if this is related. Does anyone have a suggestions?
